我正试图将CSV导入MYSQL数据库。我在这里遵循了一个教程
现在我得到一个错误，
下面是我的控制器代码:您要上传的文件类型是不允许的。
function importcsv() {
$data['addressbook'] = $this->csv_model->get_addressbook();
$data['error'] = ''; //initialize image upload error array to empty
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'text/x-comma-separated-values'|'text/comma-separated-values'|'application/octet-stream'| 'application/vnd.ms-excel'|'application/x-csv'|'text/x-csv'|'text/csv'|'application/csv'|'application/excel'|'application/vnd.msexcel'|'text/plain';
$config['max_size'] = '1000';
$this->load->library('upload', $config);
// If upload failed, display error
if (!$this->upload->do_upload()) {
$data['error'] = $this->upload->display_errors();
$this->load->view('csvindex', $data);
} else {
$file_data = $this->upload->data();
$file_path = './uploads/'.$file_data['file_name'];
if ($this->csvimport->get_array($file_path)) {
$csv_array = $this->csvimport->get_array($file_path);
foreach ($csv_array as $row) {
$insert_data = array(
'firstname'=>$row['firstname'],
'lastname'=>$row['lastname'],
'phone'=>$row['phone'],
'email'=>$row['email'],
);
$this->csv_model->insert_csv($insert_data);
}
$this->session->set_flashdata('success', 'Csv Data Imported Succesfully');
redirect(base_url().'csv');
//echo "<pre>"; print_r($insert_data);
} else
$data['error'] = "Error occured";
$this->load->view('csvindex', $data);
}
}
public function chk_attachment() // callback validation for check the attachment extension
{
$file_type = array('.csv');
if(!empty($_FILES['uploaded_file']['name']))
{
$ext = strtolower(strrchr($_FILES['uploaded_file']['name'],"."));
if(in_array($ext,$ext_array))
{
return true;
}
else
{
$this->form_validation->set_message('chk_attachment','Attachment allowed only csv');
return false;
}
}
{
$this->form_validation->set_message('chk_attachment','image field is required');
return false;
}
}
回调函数是由stackoverflow上的一个用户建议的，他解决了同样的问题，但不知何故对我不起作用。我有一个用户表，我只是想用上传的CSV插入用户，但不知何故，它不允许我上传CSV。

添加$config['allowed_types'] = 'csv';到$config数组
更多帮助请查看https://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html
也可以通过文件路径应用程序configmime .php来更清楚地了解文件上传类型
对csv数组的支持如果你真的需要，你可以更新这个数组
'csv' => array('text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel')
